Synthesis of TiO_2/Polymer Composite Microspheres Using Functional Porous Polymer Particle as substrate

摘要

This study described a different nano-titania(TiO_2)/polymer composite where TiO_2 were uniformly deposited on the porous poly(styrene-divinyl benzene-comaletic anhydride) [poly(st-DVB-co-MAH)] microspheres. The morphology of the composite microspheres was analyzed by scanning electron microscope and X-ray diffraction. Both the diameter of the pore and the MAH functional groups played a crucial role in controlling the structure of TiO_2 shell. The rutile nanoparticles were incorporated evenly onto the surface of the porous microspheres when microspheres with pore diameter of about 146.8 nm and with surface 30 wt% functional groups (MAH) were used as substrate.
